Installing Nodejs 18 on Centos Stream 8/9 AlmaLinux 8/9 RockyLinux 8/9

Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a web browser. It allows developers to build server-side applications using JavaScript, which was traditionally used only on the client-side.

One of the key features of Node.js is its non-blocking, event-driven I/O model, which allows applications to handle a large number of concurrent connections with relatively low memory overhead. This makes it well-suited for building real-time applications like chat applications, online games, and collaborative editing tools.

Please note from version 18, Centos 7 is not supported due to older version of dependencies.
